transformer solution for pectrochemical industry Drilling platform and box-type substation [Jan 12,2016]
transformer solution for pectrochemical industry Drilling platform and box-type substation
Power distribution solution of pectrochemical industry is mainly specific to the driving force in petrochemical industry system. Distant 10kV power supply provides power distribution box,power distribution cabinet and prefabricated substation equipments to form power distribution solution. The driving force is 8PT LV driving force system, distant 10KV power supply adopts prefabricated substation, use 10kv circuit to cover the entire oil field.
1.
8PT low voltage driving force system
Nominal parameters:rated current ,6300A; rated voltage, 380V/660V; rated frequency, 50HZ; short circuit withstand current, 100KA;overhead type busbar,3-phase five-wire system. The cabinet body adopts sheet steel and bend it. The level of protection is IP54, which has dust proof and water proof function. The incoming  line adopts frame circuit breaker, outgoing line adopts plastic shell circuit breaker, drawer type or fixed separate structure to facilitate repair and replacement.
2.The scheme of box-type substation
The box-type substation is mainly used for distant power transmission to petroleum wild field for use. It has the advantages of compact structure, small cover area, low investment,etc. the box-type substation comprises of high voltage RMU,transformers and low voltage power distribution cabinets.

drilling platform and box-type substation.In the system, HV cabinet adopts HXGN-12 fixed type RMU, transformer adopts SM11 series full closed type oil immersed transformers or SCB series dry type transformer, LV cabinet adopts GGD series fixed type LV power distribution cabinet.
HV RMU adopts single busbar single power supply service. The system comprises incoming cabinet, metering cabinet and transformer cabinet. HV main switch adopts SF6 loading switch, short circuit breaking capacity is 20KA. Metering cabinet is installed with PT and CT inside, it can be used for HV metering. Transformer cabinet has fuse protector.HV load switch is manual switching and closing type and has anti-thunder surge arrestor
at transformer HV side is cable connection, LV side is copper busbar connection, and with high-voltage cabinet linkage has gas protection,with LV cabinet linkage has overheating protection.LV cabinet adopts single busbar and single incoming line. The function of power distribution cabinet mainly includes incoming line cabinet,capacitance compensation cabinet and outgoing line cabinet. The main switch adopts frame type circuit breaker, feeder adopts plastic shell type circuit breaker with overloading protection function and surge arrestor. In order to meet special requirements due to far away from dwelling district,the substation is equipped with resting room and air condition equipments. Due to the bad road situation around the oil field,box-type substation adopts modular design, segment transportation and site installation to provide convenience for the transportation and usage.
